Export saves incorrect markers in 1.9.0

[onazaruk]

Export command:
poetry export --only acceptance --without-hashes > acceptance_reqs.txt

pyproject.toml

[tool.poetry.group.acceptance.dependencies]
python = "^3.11.7"
behave = {version = "1.2.6", markers = "python_version >= '3.11' and python_full_version < '4.0.0'" }

Version 1.8.0 output:

behave==1.2.6 ; python_full_version >= "3.11.7" and python_full_version < "4.0.0"

Version 1.9.0 output:

behave==1.2.6 ; python_version >= "3.12" and python_full_version < "4.0.0" and (platform_system == "Windows" or platform_system == "Darwin") or python_version >= "3.12" and python_full_version < "4.0.0" and (platform_system != "Windows" and platform_system != "Darwin")

Poetry version 2.0.1
Expected python version constraint is >= "3.11"
Is that a bug, or am I missing any extra configuration for v1.9.0?

I cannot reproduce. Can you provide a minimal (complete) pyproject.toml?

By the way, your snippet looks wrong: It shows a dependency group with a python constraint. The python constraint should be in tool.poetry.dependencies.
